There are numerous projects which have limited activity and have not been closed because of ongoing maintenance work items. For example, projects that have spawned ASTM or other standards need to be maintained (revisions, ILS, etc...). These projects don't warrant individual meetings and budgets but there are still ongoing activities. To manage these work functions these projects have been combined into a single project identified as "Project Maintenance Activities". This consolidated project has been given a budget to manage the various sub-projects.
